Vallø Castle, located seven kilometers south of Køge in Stevns Municipality, Denmark, traces its origins to the 14th century and represents a striking Renaissance fortress with robust red-brick architecture. Originally constructed as a noble residence in 1580, it was transformed in 1737 into a royal foundation for unmarried women of aristocratic birth. After a devastating fire in 1893, the castle was meticulously rebuilt while preserving its iconic exterior and surrounded moat. Today it serves as a residence for Vallø stift, a charitable home for unmarried, widowed, and divorced women of noble descent. The 4,109-hectare estate includes extensive woodlands and visitors are welcome to view the castle courtyard and explore Slotsparken, the surrounding public park.
